Okay, so why does madVR not change the refresh rate to 24/1.001Hz or engage smooth motion (on a 60Hz display)? Forcing deinterlacing & film mode where it detects a 3:2 pattern on the clip seems to be the only way to get it to actually treat it like p23.976 content.

Improving the anti-ringing of sharpen edges would be welcome. At 1080p -> 1080P, I like to use a small amount of sharpening to keep the appearance of the image consistent across all resolution profiles. I find sharpen edges looks the best when used alone because it doesn't alter image brightness, but it shimmers during panning scenes due to its ringing. It is really my last request after a year and a half of using madVR. Super sampling or another sharpening algorithm that resembles SuperRes would also be welcome.

Also, I mentioned earlier that peak luminance should have a disclaimer next to this setting to the effect: "For HDR content mapping." Most people, like me, won't even know where to begin and would assume this applies to all content.

This is why I still use avisynth at the moment. @ madshi I think it could be interesting to use upscaling refinement even without upscaling or add a similar option for post sharpening. |

MadTPG
I guys,
I'm running madVR 0.89.17 on a Pc with Win7 64bit. I use this HTPC on an OLED UHD LG TV. This tv do not support directly 0-255 levels so I set madVR to work in 16-235. I've done a simple test... I used Calman 5 and madTPG like pattern generator and measured a full 21 steps grey scale. the result is this: After that I turned back in madvr >> "color & gamma" and I set brightness to +50. When I set +50 I've madvr displaying a near black flashing bar test pattern. The +50 have an evident effect on the flashing bars ... I turned back in madTPG and with Calman I performed another grey scale read ... the result is identical like before!! Maybe I found a bug? or it is normal that a brightness setting do not effect the patches reproduced in madTPG ??? thank you all for any clarification. |

Hi guys, I have a question semi-related to madVR;
I have the flagship 65" JS9505 TV from Samsung, 10bit panel. Using HDMI via a Marantz SR6010 receiver and GTX980Ti so 10-bit and/or 4:4:4 RGB is supported. However, seems like the current standard does not accept 4K @ 60Hz and RGB 4:4:4 coupled with 10-bit? At least I can't choose it in the nvidia control panel. If I go 4:2:2 I can choose 10 or 12bit. What would your recommendations be? Go with 4K 60Hz RGB 4:4:4 8bit or Ycbcr 4:2:2 12bit (10bit in madVR)? Not much (any) 10-bit content nowadays but in the future when HDR rec2020 comes, will that change the preferred settings?

HDMI doesn't have enough bandwidth for 4K RGB 4:4:4 in 10-bit, only 8-bit, or lower refreshrate, or lower chroma.
Unless movies actually start being 60Hz or something at some point, using 24p in 10-bit is probably best. Speaking of, I wonder if this is a viable setup and the resolution switcher can actually deal with it.... Switching between 60Hz 8-bit and 24Hz 10-bit automatically.

madshi himself has also just recently said that his primary focus is on TVs or Projectors, not PC-focused displays, so unless a TV actually adopts something like this at some point....

Now that I've tried ffdshow's nice, but slow version I'm really hooked to non-linear scale 4:3 or widescreen content to my 16:9 display ... but anything above sd resolution is a no go with my 2ghz dual-core. Esp. watching an old 4:3 tv series in widescreen is amazing. Btw I also tried Cyberlink's version and it's horrible b/c zero config options how strong the distortion to the edges is to be. Their version shows that there is a large speed improvement possible over ffdshow though, that's why I wondered about MadVR.

Would be awesome if this could be managed automagically

I would expect more films in UHD Blurays to be HFR - high frame rate - like what was offered in The Hobbit in cinemas. In my test library of different video footage, all of my 60 FPS UHD HEVC content is from productions that are broadcast TV. According to double blind studies its very difficult to see the difference in full chroma res vs chroma sub sampling for film content. Apparently the human eye is sensitive to black and white more than colour. Cheers |

Yes, in many scenes I literally can't tell the difference between bilinear chroma upscaling and NNEDI3-256. Someone did link a video where the difference is easily visible, however (if you pause it and look close, admittedly - but the difference isn't subtle), so it depends very much on the material.

Except that even in the cinema that's not the case. hobbit was the only movie where this was used so far. Unless more movies start using this in the cinema already, BDs also won't have it.

Like Ver Greeneyes said, it really highly depends on the content. I know it is very noticeable on pixel art like NES games where 1 color is used on 1 pixel to show it's a light or something and the subsampling kills the color.
